HTML, also known as Hypertext Markup Language, is the standard markup language used to create web pages and applications.
Along with Cascading Style Sheets (CSS) and JavaScript, HTML forms a triad of cornerstone technologies for the World Wide Web.
Web browsers receive HTML documents from a web server or local storage and render them into multimedia web pages. It also provides a means of creating structured documents by identifying clear structural semantics for text such as headings, paragraphs, quotes, links and other items. HTML elements are defined by tags, written using angle brackets.
HTML can also embed programs written in a scripting language such as JavaScript, which affects the content and behaviour of web pages. The inclusion of CSS then defines the look and layout of the content.
